Modeling the Migration and Growth of Shewanella Oneidensis MR‐1 in a Diffusion‐Dominated Microfluidic Gradient Chamber Under the Influence of an Antibiotic Concentration Gradient

Biotechnology and Bioengineering, Volume 122, Issue 7, Page 1840-1855, July 2025.
The authors investigate how Shewanella oneidensis navigates toxic environments to access nutrients in a simplified soil environment, combining modeling and experimental data. Their results reveal that motility, rather than chemotaxis, enables bacterial migration into antibiotic‐laden zones to reduce nitrate, suggesting a key mechanism for pollutant ...
